Definition

A term used to describe cancers that occur between birth and 14 years of age. Pediatric cancers are very rare and may differ from adult cancers in the way they grow and spread, how they are treated, and how they respond to treatment. The most common types of pediatric cancer are leukemia, brain and spinal cord tumors, lymphoma, neuroblastoma, Wilms tumor (a type of kidney cancer), retinoblastoma, and cancers of the bone and soft tissue. Also called childhood cancer.
